I'm missing the magical clone of the wizard. I have look everywhere but I can't find it. I have seen some people that have it. Can anyone  help me? Please :(

Just a small hint, try increasing affinity with Horace :)

if that wasn't clear, you gotta build up Horace's affinity to its 2nd lvl then you go on a quest with him to steal the key to the library, once you do you can get into the library after dark and take on the Horace copy there.
